The most common procedure of rhinoplasty is the implantation of a synthetic prosthesis. However, the complications, especially postoperative infection, could lead the suboptimal aesthetic outcome, economic losses and health threats. There is currently little literature providing an incidence of rhinoplasty infection and microbiological and antimicrobial resistance situations.
Therefore, we performed a retrospective observational study which included 173 patients who received a rhinoplasty from 1 January 2015, to 31 December 2019, in the department of plastic surgery of a tertiary hospital in Guangzhou, China. The samples from the infection site were collected and performed the bacterial culture. The antimicrobial susceptibility testing was performed by VITEK and minimum inhibition concentration testing. The whole-genome sequencing was performed by Illumina Hiseq4000 platform.
We found that eight (4.6%) patients were infected by (6), (1) and (1), of which are susceptible to most antimicrobials. Remarkably, RS1231 was resistant to colistin and polymyxin B which conferred by locating on an IncI2 plasmid with 59,170-bp sequence length. Through sequence comparison, we speculate that the pRS1231S-MCR-1 was derived from animal sources. Besides, RS1231 belongs to ST131 O25H4-fimH22 pandemic subclone and phylogroup B2, which can induce a broad variety of infections.
Our study provided a rhinoplasty infection incidence, microbiological and antimicrobial resistance prevalence data, and revealed, to our knowledge, the first case of postoperative infection of rhinoplasty by -positive, highly susceptible, and remarkably virulent isolate.

We determined the MDR profiles, antibiotic resistance factors, virulence gene complement, and hypermucoviscous features of 200 clinical isolates from two major tertiary care hospitals in Islamabad and Rawalpindi, Pakistan.
Susceptibility profiling and phenotypic analysis were performed according to the CLSI guidelines. Genetic determinants of antibiotic resistance and virulence were detected by PCR. Biofilm formation analysis was performed by microtiter plate assay.
The isolates displayed a high degree of antibiotic resistance 36% MDR-CRKP; 38% carbapenem resistance; 55% gentamicin resistance; 53% ciprofloxacin resistance; and 59% aztreonam resistance. In particular, the level of resistance against fosfomycin (22%) and colistin (15%) is consistent with previous reports of increased resistance levels. Combined resistance to carbapenem and colistin was 7%. Genetic factors assm Pakistan.
This report highlights carbapenem-resistant K. pneumoniae (CRKP) prevalence, emerging resistance to fosfomycin, and the presence of mcr-1 and mcr-2 in colistin-resistant isolates. https://www.selleckchem.com/products/Trichostatin-A.html Further, the detection of rmpA signifies the prevalence of the hypermucoviscous trait in CRKP clinical isolates from Pakistan.[This corrects the article DOI 10.2147/SCCAA.S253108.].[This corrects the article DOI 10.2147/OTT.S246031.].There is increasing evidence that non-coding RNAs (ncRNAs), including long non-coding RNAs (lncRNAs) and microRNAs (miRNAs), produce a critical regulatory effect on osteosarcoma (OS). LINC01278, as a newly discovered lncRNA, is found to be highly expressed in OS, but its related mechanism remains unclear. This research, therefore, is designed to study the mechanism of LINC01278 in OS and to find potential targets for clinical use.
qRT-PCR was applied to determine the relative expression of LINC01278 and analyze its diagnostic value in OS. CCK-8, Transwell and flow cytometry were utilized for the determination of cell proliferation, migration/invasion, and apoptosis. RIP and RNA pull-down experiments were used to verify the targeted binding effect of miR-134-5p and LINC01278. The relationship between miR-134-5p and LINC01278 or KRAS was analyzed using dual luciferase reporter gene. The effects of LINC01278 on tumor growth in nude mice was analyzed by in vivo experiment.
qRT-PCR showed that LINC01278 increased in OS tissues and serum, indicating poor prognosis. In addition, LINC01278 was also of high value for OS diagnosis. Functional experiments showed that LINC01278 inhibited KRAS-mediated OS cell proliferation and metastasis through miR-134-5p. Finally, the results of an in vivo animal model indicated that LINC01278 promoted OS growth.
LINC01278 is expressed highly in OS, and patients with high LINC01278 expression have poor prognosis. Moreover, LINC01278 can suppress the proliferation and apoptosis of OS cells through mediating miR-134-5p/KRAS axis, which is expected to become a potential therapeutic target for OS.

However, elevated polyamine levels are associated with a slew of pathological conditions, including multiple cancers. Intracellular polyamine levels are primarily controlled by the autoregulatory circuit comprising two different protein types, Antizymes (OAZ) and Antizyme Inhibitors (AZIN), which regulate the activity of the polyamine biosynthetic enzyme ornithine decarboxylase (ODC). While OAZ functions to decrease the intracellular polyamine levels by inhibiting ODC activity and exerting a negative control of polyamine uptake, AZIN operates to increase intracellular polyamine levels by binding and sequestering OAZ to relieve ODC inhibition and to increase polyamine uptake. Interestingly, OAZ and AZIN exhibit autoregulatory functions on polyamine independent pathways as well. A growing body of evidence demonstrates the dysregulation of AZIN expression in multiple cancers.
